[jira] [Created] (SOLR-2574) Add SLF4J-nop dependency

Add SLF4J-nop dependency
------------------------

                 Key: SOLR-2574
                 URL: https://issues.apache.org/jira/browse/SOLR-2574
             Project: Solr
          Issue Type: Wish
            Reporter: Gabriele Kahlout
            Assignee: Ryan McKinley
             Fix For: 1.4


After lots of discussion, we should consider using SLF4j to enable more flexibility in logging configuration.

Ceki Gulcu commented on SOLR-2574:
----------------------------------

Note that SLF4J-enabling your library implies the addition of only a single mandatory dependency, namely slf4j-api.jar. As of SLF4J 1.6, if no binding is found on the class path, then SLF4J will default to a no-operation implementation. See also http://slf4j.org/manual.html#libraries

[jira] [Updated] (SOLR-2574) Add SLF4J-nop dependency

    Assignee:     (was: Ryan McKinley)

So you are suggesting that solrj should ship with no-opp?

I'm not sure that is great behavior -- the point of SLF4j to let people choose what framework to use...

-----------------------------------

    Description: 
Whatever the merits of slf4j, a quick solrj test should work. 

I've attached a sample 1-line project with dependency on solrj-3.2 on run it prints:
{code}
java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
	at org.apache.solr.client.solrj.impl.CommonsHttpSolrServer.<clinit>(CommonsHttpSolrServer.java:72)
	at com.mysimpatico.solrjtest.App.main(App.java:12)
{code}
Uncomment the nop dependency and it will work.
